I have a problem with overriding an entity. I need the field emailCanonical to be not be unique.

Here is what I've done: In my UserBundle\Resources\config\doctrine\User.orm.xml I've added the following attribute-overrides configuration, according to the Doctrine2 documentation

<attribute-overrides>
    <attribute-override name="emailCanonical">
        <field column="email_canonical" unique="false" name="emailCanonical" />
    </attribute-override>
</attribute-overrides>

Then I ran the following console commands

$ php app/console doctrine:migrations:diff
$ php app/console doctrine:migrations:migrate

Everything worked fine. emailCanonical was made non unique. But now, when I need to generate an entity in other bundles of project, I have a strange error:

 $ php app/console doctrine:generate:entities SkyModelsBundle:Category
 Generating entity "Sky\Bundle\ModelsBundle\Entity\Category"

 [Doctrine\ORM\Mapping\MappingException]
 Invalid field override named 'emailCanonical' for class 'Sky\Bundle\UserBundle\Entity\User'.

 doctrine:generate:entities [--path="..."] [--no-backup] name

However, if I remove the override settings from xml mapping, everything works fine.

symfony doctrine-orm fosuserbundle
